Bone marrow edema pattern in advanced hip osteoarthritis: quantitative assessment with magnetic resonance imaging and correlation with clinical examination, radiographic findings, and histopathology

Abstract

The amount of BME in the OA hip, as measured by MRI, correlates with the severity of pain, radiographic findings, and number of microfractures.

Parafoveal Chondral Defects Associated with Femoroacetabular Impingement

“…The focal chondral defects noted in our patients, especially those whose lesions were associated with cystic subchondral changes, are similar to global clinical pathologic and radiologic findings associated with end-stage arthrosis [20]. Nevertheless, the mean Tegner-Lysholm score at 29-month followup was 7.4, representing the capacity to participate in competitive-level athletics.…”

Clinical outcomes in relation to locations of bone marrow edema lesions in patients with a subchondral insufficiency fracture of the hip: a review of fifteen cases

“…9 These findings can be seen in patients with osteoarthritis of the hip. 10 In the present study, 7 (47%) of 15 hips showed the BME lesions in both the femoral head and acetabulum. In contrast, no cases showed a low-intensity band (fracture line) on MR images in both the femoral head and acetabulum.…”

Osteoarthritis revisited—again!

“…A few publications have demonstrated clearly that this was not the case and that BMLs are histologically much more complex with fibrosis, cellular infiltration, and bony damage including micro fracturing. Edema was not a significant feature [13,14]. That is not to say that bone marrow edema does not occur in other conditions, such as acute trauma, but in OA the pathology is different.…”
